Ask a longtime Glen Arbor seller about the well and septic inspection required before closing, and most won't blink. They've known about it for over a decade. Ask a buyer who just closed on a three-bedroom lakefront cottage and wants to add a fourth bedroom for the grandkids, and the conversation changes fast. The inspection they passed to buy the place has almost nothing to do with the permit they now need to expand it.
That gap, between what the transfer inspection checks and what a renovation actually requires, is the part of this rule that still catches people. And it matters more in Glen Arbor than almost anywhere else in Leelanau County, because Glen Arbor's housing stock skews toward exactly the kind of property where it comes up: small legacy cottages built decades ago, now being bought by families who want more room.
A Rule Glen Arbor Wrote Before The County Did
Glen Arbor Township adopted its own Point-of-Sale Well & Septic Inspection ordinance effective June 17, 2014, becoming the second township in Leelanau County to require an inspection at transfer, following Empire Township's ordinance the year before. Leelanau County as a whole didn't follow with a unified mandate until January 2023, when the Benzie-Leelanau District Health Department's sanitary code took effect countywide.
The Glen Lake Association, which tracks water quality on Big Glen, Little Glen, and the Crystal River that connects them to Lake Michigan, has noted that three of the four townships ringing the watershed had already enacted these inspection requirements before the county caught up. Glen Arbor was one of them.
Rob Karner, a biologist who has worked with the Glen Lakes Association, put it plainly when the county was still debating whether to act: "Fortunately, in Glen Arbor, we have a township ordinance that requires an inspection upon transfer of title." That head start is why a Glen Arbor seller today isn't walking into anything new. The market absorbed this risk years before it became a county rule, and the properties that were going to fail an inspection largely already have, at some prior sale, over the last twelve years.
What The Inspection Actually Checks
The transfer inspection itself is narrower than most sellers expect. It is not a renovation feasibility study. It's a snapshot of whether the existing system is working right now. Inspectors look for specific, legally defined failure conditions: sewage backing up into the structure, effluent surfacing on the ground, a structurally failed tank, liquid sitting above the outlet invert, or direct discharge into a lake or stream.
A few practical details shape how this plays out at closing:
- Septic evaluations are valid for 36 months and water sample tests for 6 months. A system evaluated within that window at a prior sale may not need to be redone.
- Only an evaluation performed by the Benzie-Leelanau District Health Department or a NAWT-certified technician carries legal standing. A pump-out receipt from a local service company, however recent, does not satisfy the requirement.
- There is no distance-from-water exemption. Every property in the county with a private well or septic system needs an evaluation before transfer, whether it sits directly on Big Glen Lake or well back on a large inland parcel.
- Older systems that are functioning are grandfathered in. The rule does not require a working septic system to be rebuilt to current construction standards just because a title is changing hands.
Eric Johnston, who directs environmental health for the BLDHD, was candid about what these inspections had turned up countywide in a 2022 interview: at that point, township inspection programs across Leelanau were running "right around a 20 percent failure rate," with Johnston noting "we've probably seen 70 of them that aren't acceptable" out of roughly 355 inspections done since 2014. That track record, close to one in five systems needing corrective action, is part of what the county was looking at when it decided to make inspections mandatory everywhere.
The Bedroom Count Problem
Here is where the transfer inspection and the renovation permit stop being the same conversation. Septic systems in Leelanau County are sized by bedroom count, not by square footage. A cottage can pass its point-of-sale inspection cleanly, prove the system is functioning exactly as designed, and still be legally undersized the moment a buyer wants to add a bedroom.
Any change that increases wastewater generation counts as a change of use under the BLDHD's sanitary code, and that list is broader than most buyers assume: adding bedrooms, expanding a footprint, adding an outbuilding with plumbing. When that happens, the health department doesn't rely on the old transfer inspection. It runs a separate remodel review, or a file review of the original permit, to determine whether the existing system can legally support the new use. If it can't, the system has to be upgraded before the addition can be permitted, regardless of how recently it passed at closing.
For a lot of buyers in Glen Arbor, this is the actual cost surprise. Not the inspection at closing, which has been standard here since 2014 and is usually priced into the deal one way or another. It's the second look that happens a year or two later, when the addition gets designed and the septic system that passed at sale turns out to be sized for the cottage's original three bedrooms, not the four the new owners want.
What This Means If You're Selling
If you're preparing to list a Glen Arbor property, the practical move is to get the evaluation started as soon as the listing agreement is signed, not after an offer comes in. If your system was evaluated within the last three years at a prior sale, that evaluation may still carry legal weight and save time. If it's been longer, build the lead time into your timeline, since only the BLDHD or a NAWT-certified technician can perform the inspection that actually counts.
If your system is older and has never needed corrective action, the grandfather clause is genuinely on your side. Passing the inspection does not require modernizing a system that already works. The bar is function, not vintage.
What This Means If You're Buying
If you're eyeing a legacy cottage on Big Glen, Little Glen, or the Crystal River with plans to expand it down the road, don't read a passed transfer inspection as a green light for the addition. Pull the original septic permit before you finalize any renovation plans, since that record shows the bedroom count and capacity the system was actually built and approved for. A septic system's drainfield can reasonably be expected to last around 25 years or more with normal use, but age isn't the same question as capacity. A well-maintained thirty-year-old system sized for three bedrooms is still a three-bedroom system.
Why Any Of This Was Worth Doing
The reason Glen Arbor pushed this rule through in 2014 wasn't paperwork for its own sake. Failing septic systems are a documented driver of nutrient pollution in lakes, and in an 18-year data set reported in 2022, Big Glen Lake's phosphorus levels averaged close to 4 parts per billion with a slight downward trend, a sign that fertilizer and septic runoff into the lake have stayed in check. That's not an accident on a lake this developed. It's the kind of outcome a decade of transfer inspections, however unglamorous, actually produces.
A Few Questions Sellers And Buyers Tend To Ask
Does every Glen Arbor property need this inspection before it can sell? Yes, if it has a private well or septic system, which describes the large majority of homes in the township and the county. Properties fully served by municipal sewer and municipal water are the exception, and those are concentrated in a handful of villages elsewhere in the county, not Glen Arbor.
How long does an inspection stay valid? A septic evaluation holds for 36 months. A water sample test holds for 6 months. If either has lapsed by the time you're ready to close, it needs to be redone.
My system is old but has never failed. Do I need to upgrade it to sell? No. The grandfather clause protects functioning older systems from being forced into current construction standards purely because of a sale. Corrective action is only required if the system is actually failing.
